So what's the story?

I was looking at products made by site sponsor, SUPERIOR BARRELS, and noticed that they use the .223 Wylde chambering instead of 5,56mm.

School me... but be gentle...

A Wylde chamber, which is a mix between .223 and 5.56. The 5.56x45 NATO is NOT exactly the same as a .223 Rem. The 5.56 spec allows for slightly longer chambers for higher pressures. The .223 has a tighter chamber around the neck and is shorter which allows for a bit better accuracy. You can shoot .223 ammo in a 5.56 chamber, but it is DANGEROUS to shoot 5.56 (surplus for instance) ammo in a .223 chamber. What the Wylde chamber does is allow for 5.56 ammo with slightly tighter chamber for better accuracy. So you can shoot both 5.56 and .223 safely with good accuracy.

Beautiful description.

OK cool.

I know the differences between 5,56mm and .223, but had no clue as to what the Wylde chamber was...

Thanks!

Google

I've heard that the Wylde chambering tends to be a bit more accurate, but how does it run with various ammo compared to mil-spec?
